Biofilter Structures

Engineered structures for assured, continued performance

Scope

Biofilter shells can be supplied and installed as basic shells for your fit out, or as more complete constructions including media floors and spray pipework.

Construction

The Biofilter shell comprises base, wall and roof panels with internal roof supports and external bracing. Horizontal tie bars are not used within the structure.

  • Precision moulded 1000mm and 500mm panels in E-glass / isophthalic polyester with 135º cure
  • Creep resistant EPDM gasket and M12 bolts at 125mm centres
  • PVCU and pultruded isophthalic GRP roof support struts
  • Hot dip galvanised external bracing system
  • Spun galvanised fasteners (external) and A4 stainless (internal)

Design

Fully detailed drawings in dwg format plus detailed calculations.

  • Panels provide FOS >6.0 against rupture to BSEN 13280:2001
  • Steelwork to BS5950-1:2000
  • Struts designed for an FOS >4.0 against buckling to BS4994:1987

Load Cases

The biofilter structure is designed for extreme practicable combinations of:

  • Process vacuum
  • Snow / access load
  • Wind load
  • Media weight and lateral thrust

Hatches
